Thank you @xjbhenry (xjbhenry)! His fix [21](https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1752938/comments/21), helped me for my NVIDIA card. Instead of "llvmpipe (LLVM 6.0, 256 bits)" the active OpenGL renderer is now: $ glxgears -info Running synchronized to the vertical refresh. The framerate should be approximately the same as the monitor refresh rate. GL_RENDERER = GeForce 940M/PCIe/SSE2 GL_VERSION = 4.6.0 NVIDIA 396.37 GL_VENDOR = NVIDIA Corporation -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1752938 Title: Upgrading Ubuntu 18.04 disables GPU hardware acceleration To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1752938/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
